TB-500 (Thymosin Beta-4)

Thymosin Beta-4 fragment 17-47, commonly known as TB-500, is a 43-amino-acid synthetic peptide that represents the biologically active core of thymosin beta-4, a naturally occurring protein found in virtually all mammalian cells. TB-500 has been extensively studied for its role in actin polymerisation regulation, cell migration patterns, and tissue remodelling processes. Research applications span wound healing models, cardiac tissue repair studies, and connective tissue regeneration research. The peptide's molecular weight of 4963.4 g/mol and its acetylated N-terminus contribute to its stability and bioavailability in laboratory settings. At AllMyPeptides, each batch of TB-500 undergoes rigorous independent HPLC testing by third-party UK laboratories, with purity verified at 99%+. A comprehensive Certificate of Analysis is included with every order, documenting the chromatographic purity profile, molecular weight confirmation via mass spectrometry, and batch-specific quality data. Available in 5mg and 10mg lyophilised research vials.
